Selling Land to a Developer in Utah County

How do developers decide what your land is worth?

A builder works backward. They estimate what the finished lots or homes will sell for, subtract the cost to build roads, utilities, and homes, subtract their profit and risk, and what is left is what they can pay for your land. That is called the residual land value.

That is why two parcels of the same size can sell for very different prices. What moves the number most:

• Zoning and density: how many lots or units the city will allow.
• Water: whether water rights or shares come with the land, and what the city requires.
• Utilities and access: how far sewer, culinary water, power, and a public road are from your property.
• Topography and soils: slopes, wetlands, and fill all add cost.
• Timing: how long approvals will take, because time is money for a developer.

Before you take an offer, it helps to know the lot count and finished-lot values the developer is likely using.

How are land deals with developers structured?

Price is only half of a land deal. The structure decides how much of that price you actually receive, and when. These are the structures we see most in Utah County. Timeframes are typical, not guaranteed:

The riskier structures can pay much more, and they need careful contracts. Always have a real estate attorney review a land agreement.

What happens to greenbelt when you sell to a developer?

Much of Utah County's open land is assessed under Utah's Farmland Assessment Act, known as greenbelt, which taxes farm ground at its agricultural value instead of its market value. To qualify, land generally has to be at least 5 contiguous acres in active farm use for the two prior years.

When the land stops being farmed or changes use, as it will when a developer builds, a rollback tax is due:

• It equals the difference between the greenbelt tax that was paid and the full-value tax that would have been paid.
• It covers up to the last five years.
• It is due within 60 days of the county assessor's notice, and it is a lien on the land.
• A new owner who keeps farming can keep greenbelt by filing a new application within 120 days of the sale.

Who pays the rollback is negotiable. The law puts the lien on the land, and your purchase contract decides who actually pays it. On a large parcel, that line in the contract can be worth tens of thousands of dollars.

Do water rights matter when selling land in Utah County?

Often, a great deal. Many Utah County cities require developers to bring water to the city before they can build. If your land comes with water rights or irrigation shares, a developer may not have to buy them elsewhere, which makes your land worth more.

Two examples from 2026:

• Lehi requires water rights to be conveyed to the city as a condition of annexation, rezoning, or development: 3.69 acre-feet per acre in most single-family zones, and 7.30 in its R-3 zone.
• Highland requires 3 acre-feet of pressurized irrigation water per acre, according to city staff in 2026 planning commission minutes.

Requirements differ by city, so check the city where your land sits. You can look up water rights on record with the Utah Division of Water Rights. Keep shares and rights separate in your contract so it is clear what is being sold.

How long does it take to subdivide land in Utah?

Utah's subdivision rules for cities now live in Title 10, Chapter 20, Part 8 of the Utah Code. For single-family, two-family, and townhome subdivisions, state law sets some clear limits:

• A pre-application meeting within 15 business days of a request.
• No more than one public hearing on a preliminary plat.
• A first review within 15 business days in cities over 5,000 people, or 30 in smaller cities.
• No more than four review cycles for improvement plans.

The slowest part is usually a rezone, which is a city council decision with no state deadline, followed by engineering review. If your land needs a rezone, plan on months, and price the deal accordingly.

What taxes do you pay when you sell land?

How you sell can change your tax bill as much as what you sell for. Talk with your CPA about these before you sign:

• Capital gains versus ordinary income. Selling raw land you have held as an investment is usually a capital gain. If you subdivide and sell lots yourself, the IRS may treat you as a dealer, and the profit may be taxed as ordinary income.
• Section 1237. Individuals who subdivide can sometimes keep capital gains treatment if they meet strict rules, including a five-year holding period (unless inherited) and no substantial improvements. Starting with the sixth lot, part of each sale becomes ordinary income.
• Installment sale. If you carry financing and receive at least one payment after the year of sale, you can often spread the gain over the years you are paid. This is not available to dealers.
• 1031 exchange. Investment land can be exchanged for rental or commercial property and the tax deferred. Land held mainly for sale does not qualify. See our Utah 1031 exchange guide.

Five steps before you talk to a developer

1. Pull your parcel records from the Utah County land records and the parcel map.
2. Know your zoning and what the city's general plan says it could become.
3. Document your water: rights, shares, and any wells.
4. Check your greenbelt status and estimate the rollback.
5. Get a residual land value before you see an offer, so you know if it is fair.
